Universal Zoom is an informative, educational, and fun iPad app that explores the size and scale of the universe. It's a treat for both your eyes and your brain.

1Universal Zoom : Galaxy

The app shows the structure of our Milky Way galaxy, identifying its various spiral arms and the location of Earth relative to them.

2Universal Zoom : Water Molecule

The app's depiction of water, one of the smallest molecules.

3Universal Zoom : Moons

Our solar system has many moons, some of them the size of the planet Mercury or larger.

4Universal Zoom : Neutrinos

Neutrinos are fundamental elementary particles that don't have a discernible size as we know it, but an effective size (for some purposes) can be calculated based on the strength of their electroweak force.

5Universal Zoom : Humans

Humans, of course, are represented in this great procession of creatures and objects. A quick comparison using the app's explore tool shows that an adult giraffe is approximately as tall as three people, and that the world's tallest tree, the Hyperion Sequoia, is about as tall as 66 people.

6Universal Zoom : Galaxy Superclusters

The app includes a nicely rendered diagram showing the structure of clusters and superclusters of galaxies.
